Go Kart Clutch Working

A centrifugal clutch works, as the name suggests, through centrifugal force. The key components of a centrifugal clutch are the hub, flyweights (clutch shoes), springs, linings and housing (shown in the diagram below). The centrifugal force, created by the revolutions of the engine is transmitted through two or more flyweights.

The clutch can be driven by a number of ways depending upon the design of the machinery. One of the most common methods is by mounting the clutch onto the parallel or taper crank shaft of the engine. When the crank shaft rotates the shaft of the clutch rotates at the same speed as the engine.

The springs, flyweights and the friction material are responsible for determining the speed at which the clutch engages. Depending on the design of the machine the output from the clutch can be one of a variety drives, including but not limited to shaft, pulley, sprocket or flange.
